We posted on Tuesday about how Aaron Collins' family had started a blog about his request and how strangers had been moved to contribute money to make it happen.

Contributors didn't give just enough for one big tip, though. By the start of this week, nearly $50,000 had come in and family members were figuring they could keep leaving the big tips once a week for the next two years.

More from the conversation is due on today's All Things Considered. Click here to find an NPR station that broadcasts or streams the show. Later, we'll add the as-broadcast version to the top of this post.

Meanwhile, Seth says that six $500 tips have now been handed out. And he's posted the fourth video in the family's series.
